Doctrine - validation with associated entities - symfony

Question

I have the following associations with Doctrine:
Charge:
id
amount
adjustmentItems
Adjustment
id
date
adjustmentItems
AdjustmentItem
id
adjustment
charge
amount
There are charges, and there are adjustments. Each adjustment is made up of adjustmentItems, which are adjustments to one or more charges.
When adding a new adjustment, I am adding adjustments, and the associated items, via deserialization. Ie:
$adjustment =
["date" => "2020-12-14",
"items" => [
["charge" => 84, "amount" => 600],
["charge" => 85, "amount" => 200],
]
];
Everything works well, except I validate the charges using Assert/Valid on the AdjustmentItem::charge.
In the charge validation, I check to make sure the sum of all the adjustments does not exceed the charge amount.
However, Charge::getAdjustmentItems() does not show the just created adjustmentItems (even though the adjustmentItem shows to charge, and persisting everything works as expected).
$adjustment->getAdjustmentItems()->first()->getCharge()->getAdjustmentItems()->toArray()
is:
[]
How can I get the Charge to "see" the items from deserialization before persist for validation?

Answer 1

Calling Charge::addAdjustmentItem in AdjustmentItem::setCharge solved the issue for me.
Anyone know why this is needed?
public function setCharge(?Charge $charge): self
{
$this->charge = $charge;
// This is needed so that the Assert/Callback in Charge knows about this adjustmentItem.
$charge->addAdjustmentItem($this);
return $this;
}
